Meanwhile Apple made a choice to leave iOS 18 vulnerable on the devices that receive updates to iOS 26. If you want security, be ready to sacrifice UI usability.
It's a rug-pull going against the tradition of supporting the most recent 2 OS versions until the autumn refresh simply to technofascistly force users onto 26 with an artificially-created Hobson's false choice between security and usability. This is bullshit.
If you set Liquid Glass to the more opaque mode in settings I find iOS usability to be fine now, and some non-flashy changes such as moving search bars to the bottom are good UX improvements.
The real stinker with Liquid Glass has been macOS. You get a half-baked version of the design that barely even looks good and hurts usability.
